Pasting emoji results in 404 page

[mook-as]

It appears that trying to paste text containing emoji (or at least, 🕞 U+1F55E) fails; the paste succeeds but the result just says page not found (404).

Steps to reproduce:

• Copy 🕞 and paste into the main text area at https://paste.opensuse.org/
• Click on the Create button to create a new paste.

Expected results:

A new paste is created, containing the clock emoji

Actual results:

A 404 page; the paste is nowhere to be found.

Additional information:

I was attempt to paste console output, but the program in question emitted emoji to the console.

@miska Can you please check what's going on here?

I would guess it's because of the database configuration:

paste/system/application/config/database.php

Line 50 in b57b9f8

$db['default']['char_set'] = "utf8";

That probably needs to be utf8mb4 instead, per MySQL documentation. While I'm aware that exists, I have no idea what migration might be needed.
